Romero just finished a five-game stretch where he walked 14 batters in 28.2 innings and had a 5.65 ERA yet had a 3-2 record. In his last game he got a no-decision after allowing three runs in six IP versus the Yankees. Overall, an 80.5 percent strand rate has led to a 3.70 ERA compared to a 4.41 FIP. But Romero has been a bit unlucky with his HR/FB rate of 14.7 percent. Fortunately, he is a ground ball pitcher, with a 1.78 GB/FB ratio. That is the eighth highest GB ratio among qualified major league pitchers.

Porcello has a 3.81 ERA and a 1.288 WHIP in road starts this year compared to a 4.92 ERA and 1.528 WHIP in Comerica Park. Additionally, his SO/BB numbers are over twice as high on the road, where he sports a 2.29 mark in the category. This week he has both a home start (vs SEA) and a road game (at OAK). Porcello is 7-0 this year in games in which he has not allowed a HR. But he has allowed 17 HR this year and has a 16.7 HR/FB mark.

Haeger has allowed 26 BB in 34 IP in his brief major league career. This year the knuckleball specialist is 11-6 with a 3.55 ERA at Triple-A Albuquerque, where he is currently tied for the Pacific Coast League lead in wins and is eighth in ERA. He has a 3.61 BB/9 ratio this season in the PCL, continuing a trend of declining walk numbers one step beneath the majors. His walk numbers the previous three seasons in Triple-A: 2006 (4.13), 2007 (4.08) and 2008 (3.89).
